ABSTRACT
One hundred and fifty femoral head necrosis patients with intramedullary decompression received autologous stem cell transplantation. The blood was taken from unilateral or bilateral iliac, in each group the volumes of blood taken were 200, 300 or 400 ml respectively. The number of mononuclear cells was counted before and after centrifugation. The mononuclear cell count in subgroup of 200 ml,300 ml and 400 ml taken from unilateral iliac after centrifugation was (3. 11 ±1. 42) × 1010/L, (2. 62 ±1. 31 ) × 1010/L and(2. 13 ±. 91) × 1010/L. The concentration was significantly lower in subgroup of 400 ml than that of 200 ml (t=5. 118, P<0. 01). The mononuclear cells count in subgroup of 200 ml,300 ml and 400 ml taken from bilateral iliac was(4. 51 ±. 21) × 1010/L, (3. 89 ±. 06) × 1010/L and (2. 98 ±1. 39) × 1010/L, the concentration was significantly lower in subgroup of 400 ml than that of subgroup of 200 ml (t = 6. 446, P < 0. 01). Whether 200 ml or 300 ml or 400 ml blood were taken, the mononuclear cell count in blood taken from bilateral iliac after centrifugation was significantly higher than that from unilateral iliac(t = 3. 119,P < 0. 01; t = 5. 544, P < 0. 01 ;t = 2. 207 ,P < 0. 05). The results indicate that the concentration of isolated bone marrow mononuclear cells is higher from bilateral iliac than unilateral iliac. The concentration of isolated monocytes is reduced gradually with the increased blood volume.
